92 STUDY OF NATURAL HISTORY. 
Four years after, a celebrated botanist of Germany, 
E. Fries, equally ignorant of the previous discovery 
of M‘Leay, announced the same fact as manifested in 
the vegetable world, and which he demonstrates by a 
much more extensive analysis than had been given, 
in regard to insects, in the Hore Entomologice. It 
is not the least remarkable circumstance connected 
with this splendid discovery, that four individuals, 
in different countries, and unknown to each other, 
should all have directed their studies to the same 
object, and that all should have arrived at the same 
result: thus establishing, what had never yet been 
done, the existence of at least one universal law 
in natural arrangement, and thus raising zoology, 
for the first time, to the rank of a demonstrative 
science. 
(40.) This era, then, of our science has just com- 
menced, and here must we close our sketch. It is 
not expedient that the historian shouid continue his 
narrative, when he himself becomes an actor upon the 
stage. We therefore resign to another pen the task 
of recording the passing events in the history of our 
science, and proceed to trace its influence on the 
moral and practical duties of life.
